Centup
Centup is a unique tipping platform that splits tips between the creator and a charity of the user’s choice. It functions much like a Tweet or Like button, hanging out by a piece of content waiting for the user to click. Signup is easy, there’s a nice choice of charities, and the user can set an amount of cents to their liking. It’s a nice alternative to Flattr if you want to bring the charity element into tipping.
